Abstract

The Measurement on real situation is suitable and practical to use in School ;
measurement on practical part in a method which can evaluate real student’s ability and
attitudes. The study of this research were to develop the measurement tool in science
experimentin practical part on science and to evaluate the quality of measurement tool.
The research sample were 40 MathayomSukSa one level students of SunthonphuPittaya
Secondary School selected by purposive sampling method. The tools used in the research
including 5 observation forms on science experiment in practical part ; experiment in 1st and
2nd time to rectify forms following by reliability value of 2 observers and reliability value
of observation forms on science experiment in practical part, in 3rd experiment to find out
quality by, reliability point of 2 observers, reliability point of observation forms on science
experiment and standard error of measurement value, science experiment practical knowledge
test form ; 25 items with 4 choices each, experiment in 1st and 2nd time to rectify by
discrimination method, experiment in 3rd time to find out quality by ; discrimination
method, reliability value of science experiment practical knowledge test form and value of
standard error of measurement.
The results of the research are as follow:
1. In 1st try, observation forms on science experiment in practical part found out
that the reliability value of observers were .91 to .97, the reliability value of observation
experiment were 0.43 to 0.75 and science experiment practical knowledge test form ;
divided in 5 parts 30 items, the discrimination value of each item were 0.00-0.50, so we
selected 23 items and rectify 7 items for 2nd try.
2. In 2nd try, observation forms on science experiment found out thither reliability
value of observers were .83 to .98, the reliability value of observation forms on science
experiment in practical part were 0.61 to 0.81 and science experiment practical knowledge
test form with 30 items were selected into 25 items which the discrimination value of each
item were 0.20 to 0.60 and used in 3rd try.
3. In 3rdtry, observation forms on science experiment in practical part; the full
marks for each part from part 1-5 is 5 points and mean point were 2.40-2.44, standard
deviation value were 1.35 to 1.57, the reliability value of observers were 0.92 to 0.98, the
reliability value of observation forms on science experiment in practical part were 0.86 to
0.92, the standard error value were 0.42 to 0.49. For science experiment practical knowledge
test ; mean value were 15.74, standard deviation value were 1.54-1.90, discrimination value
of each item were 0.20-0.80, reliability value of test form were 0.63 to 0.83 and standard
error value were 0.24 to 0.29.
In conclusion, the Measurement Tool in Science Experiment in Practical Part were
qualitative by standardization, suitable and practical for measurement the science experiment
on science strand Mathayom Suksa One Level as well.
